ESLint v2.3.0 released

We just pushed ESLint v2.3.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.

Highlights

Here are some highlights of changes in this release.

Support for string severity in configs

v2.3.0 introduces ability to use strings as severity level in configuration files. Before you had to use number 0, 1 and 2 to configure rules. Now we also added ability to use strings. You can now use:

off - 0

warn - 1

error - 2

Both string and int values will work the same way

EcmaScript version 7 Support

We recently updated our parser Espree with support for new exponentiation operator. You can now set ecmaVersion to 7 under parserOptions. We also updated space-infix-ops to support new ** operator.

Improved error messaging for plugins

If ESLint fails to find a plugin required by the config file, we will now print a clear message explaining to user what needs to be done to fix this issue.
